Need help troubleshooting headlights

hey guys ,
Got up today to go to work and all of a sudden my headlights aren’t working . They worked fine on drive home Saturday night but today they won’t come on. The high beams work but low beams and parking lights do not . When I turn the switch the lights in dashboard work but lights and parking lights do not . Had to drive to work with high beams . I quickly checked fuses to see if they were blown they looked ok at a glance. I am out of town till Friday so trying to see where to start troubleshooting. My next step would prob be a relay but not sure which one? I have a 2005 Tacoma 4cyl 2wd and no dtl.

Thanks for your advice

 

Do you have anything tapping into the wires for your low beams or parking lights?

 

What do you mean by tapping ? Everything is factory done I have no mods or after market things .

 

Welcome to TW! It is more common than you would think to have simultaneous low beam burn outs. Buy a new bulb and check, or if you have a voltage detector check the low beam power at the bulb.
